Abstract
Heading impact influences on brain during a soccer game such as concussion have been repeatedly reported in the statistical or neuropsychological basis. Even though, overall evaluations or conclusions have yet to be determined because few report have discussed the heading impact in the point of mechanics inside the brain. In this paper, a numerical impact analysis between a computed-tomography oriented voxel model on human head and a soccer ball expressed by shell elements has been performed. The calculated results showed that higher Mises stress is observed at the central position of the brain while the HIC values are higher in the brain tissues near the skull.
